, PAPER-DAMPENINGMACHINE.

SPECIFICATION forming- To all whom it may concern:

Be it known that I, JoriN J. CLAUSE, of Chi cago, county of Cook, andState of Illinois, have invented certain new and useful Improvements inPaper-Dampening .Machines, of which the following is a specification.

My invention relates to improvements in means for placing the paper rollin the ma chine and removing it therefrom it has been dampened.

Heretofore paper-dampening machines have been so constructed that it isnecessary to lift the roll of paper in and out of the machine, for whichpurpose various devices have been used, such as differential pulleys,cranes, and inclined planes.

The object of my invention is to provide a paper-dampening machine intoand out of which the rolls may be moved without raising or lifting themat all, and thus at the same time dispense with the more or lesscomplicated and expensive devices heretofore employed for raising theheavy rolls of paper, and avoid the trouble and inconvenienceincident totheir BS8. l a

In the present invention the bearings for the axle of the dry roll aremounted upon two supports, guides, or frame-pieces ata suitable dis- Itance apart, so thatthe roll of paper may be suspended or rolled betweenthem. The height of these frame-pieces or supports above the floor orapproach to the machine is somewhat less than the radius of the roll ofpaper, so that as the paper is rolled into the machine the axle insertedin the center of the roll of paper will clear or come above theframe-pieces, and the plat-form or base of the machine between theseframe-pieces is depressed or inclined toward the axle-bearings, so thatas the roll of paper rolls into place its periphery will clear said baseand be supported by its axle resting on the frame-pieces or guides. theroll have side openings, so that the axle of the roll restingupon theframe may be rolled directly therein without lifting the paper. The sizeof paper rolls usually varies from about fifteen to twenty-two inches inradius,

and the depression in the base or platform beneath thebearings should bemade great enough to accommodate the larger rolls, while at the sametime the axles of the smaller ones may Appiieation filed August .32,1881. (ModelJ of the roll. 'lars a, one on each end, which serve to ad-The bearings for.

iugs for removing the axle, the upper guidebars for said cross-headbeing on a level with the bearings, so that the axle may be rolleddirectly out of the bearing onto the guide-bars and out of the machine.5

My invention will be more fully understood by reference to theaccompanying drawings, which form a part of this specification, and inwhich Figure 1 is a plan view of a device embodying my invention. Fig. 2is a side elevation. Fig. 3 is a detail sectional view of the slidingblock and bearing, and Fig. 4 is a detail side view of the tensiondevice.

In the drawings similar letters of reference indicate like parts.

In said drawings, A represents the frame of f the machine; 13, thefriction driving-cylinder; O, the dryroll of paper, and D the dampenedroll. E, which forms part of the cover of the watertank F, and ismoistened as it passes by the sponge G, the lower edge of which isimmersed in the water of the tank. J

The bearings a. for the axle a, of the dry roll are mounted on theframe-pieces or guides a in suitable sockets therein, the upper frontedge of said bearings being on a level with the upper surface of saidguides. The guides a are made tapering toward their outer ends, andtheir height issomewhat less than the radius The axle a is providedwithcoljust the roll into place as the axle is rolled forward on the guides,and to keep the same in place after it rests in the bearings while themachineis in operation. The casting a, which forms the bottom or base ofthe machine, is depressed, cut away, or inclined under the bearings a,so that the periphery of the roll will clear the. same when the rolldrops into the bearings. This depression or incline also The web ofpaper passes over the plate E serves to carry the roll into place whenthe same is rolled off thelevel of the floor in front of the machine, asthe momentum the roll acquires while supported on the inclined base willcontinue to roll it along after its axle strikes the frame-pieces orguides. The axle a is provided with a tension device for regulating thetension of the web of paper, consisting of afriction-wheel, a on the endof said axle, friction clamping-jaws a (67, operated by the adjusting-screw a from the handle a through the connecting-gears a a", a,and a. The clamping-jaw a fits loosely on the screw a said jaw bearingagainst a shoulder or jam-nut on said screw, and the clampingjaw a isthreaded to fit the screw a so that the operator, by turning the handlea, may tighten or loosen the clamping-jaws on the friction-wheel, andthereby increase or diminish the tension of the web of paper. Theintermediate gearing between the handle and adjusting-screw a isemployed simply to bring the handle into convenient position for theoperator to reach it.v

H is a turn-table, which I usually provide in front of the machine forturning the roll square with the machine, and which is speciallyserviceable where there is a limited amount of room. g

The bearings 11 for the axle I) of the moistened roll are secured to orform part of the sliding blocks or cross-heads b mounted on the frame A,and which project between the guide-bars and Z)". The bearings b are U-shaped in form, and the lower leg of each of said bearings is on a levelwith the upper surface of the guide-bars I), so that the axle of theroll will be supported on said guide-bar when rolled out of the bearing.The movable part b of the bearing is secured in place by a pin,

b. The dampened roll is pressed against the I friction driving-pulleyand allowed to recede therefrom as it increases in size by means of thechains 1) b connected with pulleys Z2 If on the shaft b, which isprovided with a friction device.

0 represents a portion of the floor or platform in the rear of themachine, upon which the dampened rolls are delivered as they'are rolledfrom the machine. The height of the guide=bars If above this floor orplatform should be a little greater than the radius of the larger-sizedrolls of paper, so that the same maybe readily rolled from said guideswithout being raised.

I claim 1. In a paper-dampening machine, the combination of 'aturntable, an inclined base or platform, side rails or guides, a (6,adapted to support the roll from its axle, and provided with bearingsfor the axle, having side openings, all arranged and operatingsubstantially as specified.

2. The combination, with the axle of the roll, provided with collars a",of tapering guides a provided with bearings having side openings, andbase a, depressed under said bean ings, substantially as specified.

8. In a paper-dampening machine, the combination, with sliding blocks orcross-heads b, of bearings I), having side openings closed by movableparts 12 with guides 1), arranged on a level with said bearings, so thatthe roll supported by the axle may be rolled from said bearings on, saidguides out of the machine, substantially as specified.
